hi,
excuse typing, baby on boob!
it may be worth metioning to doc or hv as there may be an underlying cause to your daughters problem.
i had problems as a child, as a baby i apparantly threw up lots and my mum said if she over fed by just a bit the whole lot came back!
in my teens i was diognosed with a weak stomach valve and hyatis heria, from birth, neither cause me too much probs, i just know what i can eat.(symptoms are acid reflux with certain foods/drinks, not being able to eat huge meals and feeling/being sick if i do, its rather like being pregnant!)
it is not nice being raised on indigestion remidies though!!
also there is so much c**p i foods now, and most of it aimed at children so it wont help a sensitive little tummy!
Diet is very over looked, my sons ADHD symptoms were worse when he had apple and blackcurrent squash, just that one simple thing removed from his diet made such a difference, to him and us! like i say worth looking at and then like you are already, being aware of the things she can/cant have.
good luck
